| 中文摘要:建立了测定纺织品中卡拉花醛含量的气相色谱-质谱联用方法，以甲醇为萃取溶剂，超声萃取纺织品中的卡拉花醛，萃取液直接进行气相色谱-质谱/选择离子监测法测定，外标法定量。该方法检出限为01 mg/kg，在014~2818 mg/L范围内，峰面积与质量浓度间存在良好的线性关系；当加标水平分别为071、282、705 mg/kg时，平均加标回收率为873%~961%，方法精密度(RSD,n=9)为058%~24%。该方法简便快速，准确可靠，易于操作，适用于纺织品中卡拉花醛的日常分析测试。 |

| Abstract:A gas chromatography-mass spectrometric method was established for the determination of karanal in textiles.Karanal in textiles was ultrasonically extracted using methanol as extraction solvent.The extract was then analyzed by gas chromatography-mass spectrometry in selected ion monitoring mode(GC-MS/SIM).The concentration of karanal was calibrated by the external standard method.The limit of detection was 01 mg/kg.Good linearity existed between peak area and the mass concentration of karanal in the range of 014-2818 mg/L.The average recoveries at three spiked levels of 071,282 and 705 mg/kg changed from 873% to 961%.The precision(RSD,n=9) varied from 058% to 24%.The proposed method was simple,accurate,and convenient to operate.It was appropriate for the determination of karanal in textiles in routine tests. |
